Utilisation and cost of professional care and assistance according to disability of patients with multiple sclerosis in Flanders (Belgium)

OBJECTIVES: To assess the utilisation of medical services and social (community) assistance in patients with multiple sclerosis of different disability and to calculate the direct healthcare costs to society. METHODS: (1) One hundred and eighty four patients with multiple sclerosis were classified into four grades of disability according to a simplified Kurzke disability status scale. (2) Patients were interviewed with a structured questionnaire containing questions on their sociodemographic status, the use of inpatient and outpatient medical services and pharmaceutical products during the previous year, the use of social assistance, and the purchase of prosthetics and charges for house adaptations during the previous five years. (3) Data were also prospectively collected by means of four week diary annotations of all medical and social acts and their duration. RESULTS: After correction for the disability distribution the yearly costs for the 5500 patients with multiple sclerosis in Flanders was estimated to be ECU 13106000 for ambulatory care including rehabilitation and district nursing and ECU 3234000 for pharmaceutical products. To these direct medical costs ECU 3491000 for social assistance and ECU 4938000 for prosthetics and adaptations should be added. The yearly costs for admissions to hospital including permanent residence in an institution and pharmacy was ECU 26581000 . Home nursing and long term or permanent residence in an institution of the most severely disabled, 17% of the multiple sclerosis population, are responsible for 50% of the total direct healthcare costs and care for the 6.5% institutionalised patients accounts for 23%. Direct costs for medical care and social assistance for patients with multiple sclerosis, who account for about 0.1 % of the total population, amounts to 1% of the total healthcare budget in Flanders. CONCLUSION: This information on utilisation of medical services and social assistance can be used for good healthcare planning and cost effectiveness studies.

Pharmacy database for tracking drug costs and utilization.

A pharmacy database for tracking drug costs and physician prescribing trends is described. Accuracy problems plagued data systems used to make drug-use-policy decisions at a tertiary care teaching hospital because of structural deficiencies within the systems and their nonclinical orientation. To resolve these problems, a programmer analyst, a clinical supervisor, and a clinical pharmacist developed a hierarchical database of drug costs. The database was designed to be valid for tracking drug costs according to patterns of clinical use. Internal controls were created that could identify and correct cost-tabulation errors arising within the ordering, order-entry, and billing processes. The database was able to tabulate drug costs according to the clinical service on which the patient was being treated at the time so that reports could compare aggregate prescribing trends from one time period to another for the same service. Similarly, the database could track and report drug use by disease or financial classification. Flagging elements were introduced to the database for cancer chemotherapy and antimicrobial drug products to enable reporting by these categories and by therapeutic subcategories within the antimicrobial category. Routine monthly reports were distributed to end users. Development of a database for tracking drug costs and utilization allowed a teaching hospital to derive the cost of medications from billing-charge information and to report data to health care professionals on the basis of important factors like clinical services.

Decreasing errors in pediatric continuous intravenous infusions.

OBJECTIVE: To evaluate the effect of a Web-based calculator and decision-support system on infusion ordering errors and to estimate error frequency in pharmacy infusion preparation. DESIGN: Data on ordering error frequency and typology were collected before and after implementation of an online infusion ordering system. Data on pharmacy preparation errors of infusions were collected. SETTING: A children's hospital at an academic medical center. PATIENTS: None. Data were abstracted from infusion orders. INTERVENTIONS: Introduction of a voluntary-use Web-based calculator into infusion ordering workflow. Observation only. MAIN OUTCOME MEASURES: Number and type of errors in handwritten and calculator-generated orders. Number and type of errors in pharmacy infusion preparation. RESULTS: Before calculator deployment, 129 sequential handwritten infusion orders were collected over 5 weeks. After deployment, of 162 sequential infusion orders, 88% (142) were calculator-generated. Calculator-generated infusion orders contained 83% fewer (p < .001) orders containing one or more errors than handwritten orders. Calculator-generated orders contained no high-risk errors (incorrect decimal, dose, or unit of measure) when compared with handwritten orders and were associated with fewer pharmacy interventions. In 118 sequential pharmacy infusion preparations over 4 wks, there were no errors observed. CONCLUSION: A Web-based calculator reduced significantly the total number of errors and eliminated all high-risk errors in the prescribing process for continuous pediatric infusions. With no observed errors in pharmacy preparation, this study provides data to support the use of computerized ordering as an independent safe and viable method for ordering continuous pediatric infusions.

Time trends in lipid lowering drug use in The Netherlands. Has the backlog of candidates for treatment been eliminated?

AIMS: To assess time trends in lipid lowering drug use in The Netherlands. METHODS: Data were obtained from the PHARMO-database, comprising pharmacy records of approximately 300 000 people in The Netherlands. In the period from 1991-98, we estimated prevalence of lipid lowering drug use on the first Wednesday of October. A patient was defined as incident user if (s)he filled a prescription for lipid lowering medication after a 360 days lipid lowering drug free interval. Both prevalence and incidence estimates were weighted for the sex and age distribution of the general Dutch population. RESULTS: From 1991 to 1998, the prevalence of lipid lowering drug use increased from 0.5% (95% confidence interval (CI): 0.5, 0.6) to 2.3% (95% CI: 2.2, 2.4) in women and from 0.6% (95% CI: 0.6, 0.6) to 2.9% (95% CI: 2.8, 3.0) in men. Prevalence increased with increasing age and was highest in the age category 60-69 years (in 1998: 9.9% (95% CI: 9.4, 10.4) in women and 11.6% (95% CI: 11.0, 12.1) in men). In 1992, the estimated incidence of lipid lowering drug use was 251(95% CI: 226, 277)/100,000 person years in women and 251(95% CI: 225, 276)/100,000 person years in men. The largest incidence estimates were observed in 1996 (685(95% CI: 644, 726)/100,000 person years in women and 881(95% CI: 834, 928)/100,000 person years in men). After 1996, incidence stabilized in 1997 and decreased in 1998 to 599(561, 637)/100,000 person years in women and 731(688, 773)/100,000 person years in men. Most of the patients (approximately 95%) were treated with one lipid lowering agent. Statins were used by over 90% of patients from 1996 onwards. In 1998, 35% of the patients started with a statin that was not a first choice drug (mainly atorvastatin). CONCLUSIONS: In the period from 1991-98, prevalence of lipid lowering drug use significantly increased in The Netherlands. However, incidence stabilized and decreased after 1996 which may be explained by the fact that the number of patients eligible for treatment was reached. The question remains whether lipid lowering medication was targeted to the appropriate patients.

Syringe distribution to injection drug users for prevention of HIV infection: opinions and practices of health care providers in New York City.

The Expanded Syringe Access Demonstration Program (ESAP), which was intended to increase access to syringes for injection drug users (IDUs), went into effect in New York State on 1 January 2001. ESAP allowed prescription-authorized health care providers to register to distribute syringes without a prescription. In spring 2002, we conducted a random postal survey of 1100 providers in New York City to evaluate involvement in ESAP and willingness to furnish IDUs with syringes. Among 363 nurse practitioners, physicians, and physician assistants responding, 16.9% knew about ESAP, and 2.0% believed they were registered; 50.5% would consider distributing syringes to patients who were IDUs. Most of those unwilling to distribute syringes were concerned about legal and moral issues. More respondents agreed that providers should prescribe syringes than distribute syringes (41.1% vs. 22.7%; P<.0001). These results suggest that many providers are willing to furnish IDUs with syringes but are unaware of the current law.

Evaluation of 4 years of clinical pharmacist anticoagulation case management in a rural, private physician office.

OBJECTIVES: To evaluate patient outcomes after 4 years of anticoagulation case management by a pharmacist and to document patient and provider satisfaction with the service. SETTING: Rural, private physician office in Mt. Vernon, Iowa. PRACTICE DESCRIPTION: Clinical pharmacist anticoagulation clinic. PRACTICE INNOVATION: Under a protocol reviewed annually, a clinical pharmacist faculty member from the University of Iowa College of Pharmacy provides on-site, point-of-care anticoagulation dose adjustment and monitoring 1 day per week. MAIN OUTCOME MEASURES: Data on anticoagulation outcomes from 1998 to 2002 were obtained through retrospective review of medical charts of patients served by the clinic. A survey of patient satisfaction with the clinic was mailed to all currently active patients enrolled in the anticoagulation clinic, and a second satisfaction survey was distributed to providers and ancillary staff of the physician office. RESULTS: Eighty patients met the criteria for evaluation of therapeutic outcomes. The mean +/- standard deviation percentage of international normalized ratios in the therapeutic range ("percent therapeutic") for the anticoagulation clinic population was 57.5 +/- 17.4. The percent therapeutic for patients who had been on warfarin before enrolling in the pharmacist case management anticoagulation clinic (defined as the usual medical care group) was 37.6%, compared with 57.8% for those patients receiving care in the pharmacist case management anticoagulation clinic (P < .001). In nearly all instances, responses to the surveys indicated that patient and provider satisfaction with the anticoagulation service was extremely high. CONCLUSION: A clinical pharmacist can provide anticoagulation case management services safely and effectively in a private physician office, and the service is highly valued by both patients and providers. We believe case management is an optimal method for systematically monitoring outpatient anticoagulation therapies and is preferable to usual medical care.

Prescribing medication errors in hospitalised patients: a prospective study.

The aims of this prospective study were to determine the incidence and types of prescribing medication errors and ways to prevent them from reaching patients. Data were collected from 4951 prescriptions over a 25 week period in 2002. Medication errors were classified as: incorrect dose, incorrect dose interval, duplication of therapy and drug interactions. The medical record analysis was used to compare prescribing with Croatian literature drug data and AHFS first Web version 2 (American Society of Health System Pharmacists). The incidence of medication errors in the entire sample, including all potential drug interactions, was 14.7%. However, as only 8 interactions (out of 356 potentially possible interactions) were assessed as clinically significant, then the total number of all types of medication errors was 379. This resulted in an incidence of 7.7%. Dosage errors were the most frequent errors, followed by incorrect interval, drug duplication and drug interaction. The difference between the incidence of potentially possible and clinically significant drug interactions was quite large (7.2 vs. 0.2%). Thus, a critical attitude is necessary when evaluating available data on drug interactions. Our findings point to the need of systematic control of prescribed therapies, which could be ensured by the application of the Unit Dose Drug Distribution System. A medication errors reporting program should be established both at the hospital and at national levels in Croatia.

[Pediatric medication errors and their prevention].

Two investigations, one carried out throughout France (PediAD) and the other exclusively in Robert Debré pediatric hospital (PediEM), focus on the difficulties encountered by nursing staff when administering drugs to children, and the risk of medication errors. Medication errors can arise from dysfunctions at all stages of the drugs circuit, and may involve doctors, pharmacists or nursing staff. In pediatric hospitals they are mainly related to the lack of commercial products specifically designed Jor children. In Robert Debré Hospital, only one-third of commercial products in stock are authorized for pediatric use with no age limit. Thus, even in a hospital where drug distribution is entirely computerized (PCS Patient Care System software), where dispensing is based on the DIP system (daily, individual, and personal) but is not con trolled, and where almost all requirements for sterile and non sterile preparations are met but where validation is only partial, the system is far from being error-free. Two major improvements are planned. First, dispensing will be automated in 2006. With the current shortage of pharmacy technicians, this will securitize drug dispensing and provide for therapeutic and economic traceability. Second, integration of a pharmacist within each medical team is being compared with validation of prescriptions by a pharmacist in the hospital pharmacy.

[A comparative study on drug utilization in primary care depending on the professionals and family consumers].

Information on pharmaceutical assistance in health care can be obtained from different sources: pharmacies, medical records, market studies, and family interviews. These allow to evaluate whether the consumed drugs were prescribed or directly purchased, if they are stored at home, and the relation between these facts and the familial characteristics. In the present study we have carried out a comparative analysis of data related to the use of drugs in the Salamanca Province depending of their source: the doctors or the families themselves. We distributed by post a questionnaire to the primary care physicians. We also interviewed a representative sample of the families of the Salamanca Province. We found that those drugs most commonly prescribed by doctors were also the most commonly reported as used by the families: drugs for cardiovascular disease, anti-inflammatory-antirheumatic drugs, and analgesics.

Outcome of cholesterol screening in a community pharmacy.

The purpose of our study was to determine if a community pharmacist could affect total blood cholesterol (TBC) of ambulatory patients by a program of education, consultation, and cholesterol screening. Of 241 initially screened individuals, 57 patients with TBC greater than 5.17 mmol/L (greater than 200 mg/dL) met the inclusion criteria of this six-month study. Of these, 51 completed the study. Outcome was determined by changes in TBC measured during the initial screening and after two follow-up visits. Pharmacist intervention included obtaining TBC concentrations and reporting the results to patients, teaching patients about the role of cholesterol in illness and health, explaining risk factors associated with cardiovascular disease, and providing follow-up communication with patients. Data were analyzed using ANOVA, Mann-Whitney, and chi-square. The mean TBC was 5.84 mmol/L (225.7 mg/dL) for the study group and 4.23 mmol/L (163.8 mg/dL) for participants with TBC less than 5.17 mmol/L (less than 200 mg/dL (p less than 0.0001). There was a significant difference (p = 0.0124) in mean age for the study group (36.4 years) versus other participants (30.0 years) but no difference in distribution by gender (p = 0.18). ANOVA showed significant differences in TBC during the three visits (p less than 0.0001). There was a significant decrease in mean TBC concentrations between visits 1 and 2 and between visits 1 and 3 (p less than 0.0001), but no difference between visits 2 and 3 (p = 0.48). Compared with mean baseline values, 81.4 and 72.6 percent of the patients had a decline in TBC at visits 2 and 3, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Establishment of a drug information service on a public-access computer bulletin board.

OBJECTIVE: Computerized bulletin board services (BBSs) have existed for several decades; in recent years there has been increased use and acceptance. We have established a drug information service called The Pharmacy on a local public-access BBS, the Cleveland FreeNet. The goal of this service is to provide drug information to the lay public as well as healthcare professionals. DESCRIPTION: The Pharmacy is divided into 4 areas: (1) About the Pharmacy, which provides instructions for use; (2) Drug Information, which contains postings on selected drug information topics that are prepared by the BBS staff; (3) Pharmacy Questions, the most popular feature, where FreeNet users are invited to post questions, the answers to which are provided by clinical, staff, and consultant pharmacists, as well as baccalaureate and graduate pharmacy students; and (4) Investigational Studies, where patient recruitment for investigational studies is done. RESULTS: A total of 259 questions have been posted in the first 3 years of operation. An average of 5.2, 7.78, and 8.7 questions/month have been posted in 1992, 1993, and 1994, respectively. Four drug information monographs have been prepared and posted, and approximately 5 investigational studies have been advertised. CONCLUSIONS: A computerized BBS is a new means of distributing drug information to the public and healthcare professionals. In addition to meeting a need for a public service of drug information in the community, it permits increased visibility for pharmacists and a unique learning experience for students.

Clinical training program for staff pharmacists.

This study describes the development and evaluation of a clinical training program in the areas of pharmacokinetics and infectious diseases for staff pharmacists in a decentralized unit dose drug distribution system. Five staff pharmacists were trained and three other pharmacists served as controls. The teaching sessions consisted of eight 1-hour lectures per group of two to three pharmacists. The lectures were supplemented by handouts, reading assignments, and practical assignments. There was a significant improvement in posttest scores of the trained pharmacists when compared to their pretest scores and from the scores of the control pharmacists. In the Seattle VA Medical Center pharmacy, this program was shown to be successful, and a similar program can be used to train staff pharmacists in other clinical areas of interest.

Recruiting participants for community-based research: the Diabetic Retinopathy Awareness Program.

PURPOSE: Recruiting participants is a major challenge for population studies. We present the recruitment methods followed by the Diabetic Retinopathy Awareness Program (DRAP), a community-based, randomized, masked, controlled trial to meet and exceed its sample size goals. METHODS: A county-wide multi-media promotional campaign to recruit and enroll participants in the trial was planned and executed from October 1993 through April 1994, with the assistance of the local news media and community and professional groups. A toll-free 800 number recruitment line was established, and postage-paid recruitment postcards distributed. The trial was designed to examine whether a mailed educational intervention could increase compliance with vision care guidelines among persons with diabetes in the community. RESULTS: A total of 2308 persons with diabetes were interviewed for eligibility and 813 enrolled in the intervention trial, exceeding the original recruitment goals of 1800 and 600, respectively. Those who completed the enrollment interview reflected county demographics. During recruitment, newspaper, television and radio stories featured the study; pharmacies and physician offices displayed study materials; public service announcements appeared in local print and broadcast media. The largest single recruitment response was a local television news report, followed by a newspaper story. CONCLUSIONS: These experiences substantiate the need for a comprehensive coordinated approach, using planned multiple sources, to achieve recruitment success. By engaging the lay and professional communities along with the media, recruitment costs can be kept to a minimum. Participant costs can be minimized by employing a toll-free number and eliminating study participant travel, thus allowing for inclusion of traditionally underserved populations. This approach is applicable to other studies, where community-based participation is desired.

[Acid-related disease in the population of two Norwegian municipalities--diagnosis and drug therapy].

BACKGROUND: The introduction of acid suppressant, cytoprotective and prokinetic drugs represented major progress in the treatment of acid-related diseases. In Norway, these drugs were reimbursed by the National Insurance System (NIS) from 1986. However, even if the distribution of the various diagnostic indications for prescribing were lacking, this reimbursement was stopped in 1995. The aim of this study was to describe prescriptions for presumed licensed diagnostic indications of these drugs for a defined population, and analyse them with regard to patients characteristics, verified (endoscopic) diagnoses, and therapeutic guidelines. MATERIAL AND METHODS: All prescriptions issued in 1994 to inhabitants of Lindesnes and Mandal Municipalities (17,105 inhabitants) were retrospectively retrieved from the pharmacies and the NIS. The medical records of the local endoscopy units and roentgen laboratories were subsequently searched for information on diagnostic procedures and final diagnosis leading to the prescriptions for these patients. RESULTS: A total number of 1,128 prescriptions (87,905 DDDs) were issued to 441 patients (3% of the population at risk; mean age 63 years; 55% men), and more commonly for the elderly (for 11% of those aged 80 years or more). Diagnostic procedures were documented for 93% of the patients (upper endoscopy in 404, 92%). Diagnostic indications for prescribing were reflux oesophagitis (48%), duodenal ulcer (24%), gastric ulcer (13%), and dyspepsia with normal endoscopic findings (12%). The drugs issued were H2-receptor antagonists (59%), proton pump inhibitors (31%), and cisapride (10%). 8% of the patients were long-term users of an NSAID. Of the 441 patients, drug treatment was issued to 38 with normal endoscopic findings and to 31 patients in whom we could not document examination by endoscopy or X-ray. INTERPRETATION: This study supports that the prevalence of dyspeptic complaints calling for drug treatment increases with patient age. With minor exceptions we found that the prescribing practice for the different diagnoses is in accordance with established therapeutic guidelines.

Advertising of medicines on New Zealand television.

AIMS: To measure the frequency of advertising of medicines on New Zealand television and to describe the distribution of advertising. METHODS: A stratified random sample of 35 days (577.5 hours) of television was video-recorded, including five free to air channels for each day of the week. Videotapes were watched, then advertisements were recorded on a pre-designed form. RESULTS: 340 advertisements for medicines were identified, an average of 1 per 102 minutes; 37% of advertisements were for medicines available for general sale, 24% for dietary supplements, 21% for pharmacy- or pharmacist-only medicines, and 18% for prescription-only medicines. Four channels had similar amounts of advertising. Channels varied in the kind of medicines they had advertisements for. There were more advertisements per hour in the afternoon than in the morning or evening. Advertisements for medicines were found in a wide range of programmes, including children's programmes. CONCLUSIONS: People who watch particular programmes, or who watch television at some times of days may be exposed to considerably more than one medicine's advertisement per 102 minutes. While this study does not examine the effect of medicines advertisements on consumer behaviour, previous research suggests this may be significant.

Development and implementation of simplified aminoglycoside empiric dosing guidelines.

Poor empiric dosing of aminoglycosides continues to be a problem in many hospitals. Consequently, a two-phase study was undertaken to evaluate gentamicin and tobramycin (G-T) dosing in our institution and to develop practical guidelines to achieve optimum initial G-T serum concentrations. In the pre-intervention phase (phase 1), approximately one-third of 232 G-T treatment courses were initiated with regimens that resulted in low initial serum concentrations. Empiric dosing guidelines were subsequently developed using Pharmacy Pharmacokinetic Service data and literature recommendations. They were validated with patients in phase 1. Compared with earlier dosing methods, the guidelines resulted in initial serum G-T concentrations within the therapeutic range in an equivalent proportion of patients. To simplify the procedure, recommended dosages were based on age, total weight, and serum creatinine only. The guidelines were tabular in format, and prescriber calculations were not required. Pocket and wall chart guidelines were distributed and promoted. During the post-intervention phase (phase 2), the impact of the guidelines was assessed. A review of 232 phase 1 and 203 phase 2 treatment courses revealed an increase in the initial mean dose per interval prescribed after the intervention (p < 0.01). No change in the mean interval was noted. When guidelines were followed, a higher proportion of treatment courses achieved early therapeutic serum concentrations (Cpmax 5-10 mg/L, 80% vs 54%; p < 0.005). The new empiric guidelines appear to be a practical alternative to existing methods of dosing aminoglycosides.

Unintentional ingestion of over the counter medications in children less than 5 years old.

OBJECTIVE: Childhood ingestion of medications remains a substantial problem. Medication available over the counter (OTC) is widely used and has significant toxicity. The present study aims to investigate the nature and extent of unintentional ingestion of OTC medication in children < 5 years old in Victoria, Australia, during the period 1996-2000, in order to highlight critical factors. METHODS: Numbers of enquiries relating to unintentional ingestion of OTC medication in children < 5 years old and medication types were obtained from the Victorian Poisons Information Centre for 1998-2000. Emergency Department presentations involving poisoning of children < 5 years old, the medication types and subsequent admissions were obtained from the Victorian Emergency Minimum Dataset for 1996-2000. RESULTS: Numbers of enquiries and Emergency Department attendances for poisoning were substantially higher for OTC medication than for prescription medication; however, a lower proportion of cases involving ingestion of OTC medication (24.8%) required hospital admission during the study period compared with cases involving ingestion of prescription medications (33.8%). Overall, the peak incidence was at 2 years of age, with a slight male over-representation. Paracetamol and cough/cold preparations were the most common agents. CONCLUSIONS: The causes of unintentional ingestion of OTC medications by children might include lack of child-resistant closure (CRC), inadequate design of CRC, attitudes concerning the toxicity of OTC medications, or lack of vigilance by parents and carers in the storage and administration of OTC medications. Consideration should be given to restricting sales of toxic OTC medications to pharmacies, and increasing counselling of consumers concerning the toxicity and safe storage of OTC medications and the correct usage of CRC. The adequacy of CRC design and OTC medications warranting CRC should be reviewed by the relevant authorities.
